led board module Customers Reviews

Only takes 2 wires to use. Mine was a Catalex as shown. Had seen some complaints about these devices from various sources, but no problems with this one.Used: http://www.seeedstudio.com/wiki/Grove_-_4-Digit_Display for trial sketchs and nice timer routine too.

Surprised how accurate a clock you get with just the UNO crystal and no correction. Wanted to do something each day at a time +/- a couple of min.If I have to adjust the "clock" once a week, no big deal.

Bright RGB LEDsSimple hookupUser can control two pairs of LEDsFor Arduino use ShiftPWM library

I was able to make this module work with Arduino using the ShiftPWM library from Elco Jacobs at http://www.elcojacobs.com/using-shiftpwm-to-control-rgb-leds-with-arduino/ . I only had one but I assume that the library will support daisy-chained modules. You will also need a robust 5v power supply, since the Arduino digital outputs don't have the required current to drive the module.

If you don't mind experimenting a little, I think that this module is good value for the money.

- easy to use- easy to solder- delivers 1.4A to led- 1 mode perfect for simple designs and retrofitting in old lights.

easy to solder. small diameter fits in many old lights. perfect for updating old lights. straightforward use. no problems with soldering. I used it for an xml led and it delivers 1.4Amps to the led. The use was with no problems and the driver works without geting too hot.
